UNITED STATES PATENT OFFICE- JOHN G. SULLIVAN, OFWINNIPEG, CANADA. ANTICREEPER Fon RAILWAYS.

Specification of Letters Patent.

application filed July 8,1905. Serial No. 268.826.

To @ZZ whom it may concerm' l Be it known that l, JOHN G. SULLIVAN, a. subject of the King of England, residing at Winnipeg, inthe Province of Manitoba and Dominion of Canada, have invented a new and useful Improvement in Anticreepers for Railways, of which the followingis a speciii- Ato ' the -track is laid over bogs or muskegs or on similar soft ground such creeping becomes serious. Over bogs and muskegs it isWell known that cree ing takes place to a consid'- erable extent, tllfe rails moving 'as much as eight inches during the passage of a sin le train for a short distance, varying with t `e length of the `bo up to four or five miles.

' This tendency of the rails to creep isespe- .-cially aggravated on double-track orfourtrack roads', where the traiiic over each track isv always in one direction. It is the purpose of my invention tov provide aninexpensive device which effectually resists such creeping and which can be readily ap lied to the track.

In t e accompanyin drawings, Figure 1 is a horizontal section of a portion of a track embodying the invention, the plane of 'the section being immediately below the railheads. Fig. 2 is a cross-section in line 2 2,

Fig. 1, on an enlarged scale. Fig'. 3 is a sectional topwplan view,A on an enlarged scale, of the construction shown in Fi 1. Fig. 4 is a view'similar to Fig. 1, showing a modifica-- tion of the improvement.l Fig. 5 is an enlar ed'cross-section inline 5 5, Fig. 4.

imilar letters of reference indicate corre.- sponding parts throu hout the several'views. A indicates. the rai of-one`side of a track. They are spiked or otherwise fastened to the ties B, Which'inay be of anyV suitable con. ,struction or material, the rails resting upon the customary metallic plates C.

D indicates the usual angle bars or plates which connect the adjoining rails.

Referring to the construction shown in Figs. 1, 2, and 3, E indicates an anticreeperbar arranged lengthwise on one side of the rail or railsand `rmlysecured to fthe. ties .or su ports B by ordinary spikes f or other sultab e fastenin s. This ar rests upon the base of the ra andthe ties andvextends continuously over a plurality of ties, preferably Patented J an. 2,19`Q6.

from angle-bar to angle-bar, as Shown in I 1, although in'some cases it may extend over but half that' distance or even less, according' 'to the character ofthe ground or road-bed. When the anti'creeper-barv extends 'through-r out the distance lfrom one angle-bar D to' the y next, it abuts atvboth ends agalnst -theop-f posing ends-.ofthe angle-bar'sfas vshown 1n Fig. 1; but when the anticreeper-bar extends over less than that distance 1t abutsagainst one of thev angle-bars only. On single-track roads, where the' traic -is in both directions,

. the bars E referablyabut'against` the anglebarsat bot ends, While on double-track or four-track roads, where fthe-traflic onA each track is in one direction, they abut only at f their rear ends withreference to the direction of they trafc. l

On steep grades and in bogs or muskegs,Y where the track is especially liable to creep, it

is desirable to a ply the bars E to both sides of the rails, as sliown in Figs. 4 and 5 ,fand 1n localities of that character the bars may be I extended along a greater or less number of rails, as required.

The anticreeper-bars are preferably secured to the bases of the rails between the ties by a suitable number of bolts g, having lugs g', which engage under the base of the rails, as shown in Fi 2, or by other suitable fastenings.` These olts keep 'the bars E against the base of the rails, pireventing the slale from pulling up the spi es fand ratt I- will be understood from the fore oing description that in each of the severa embodiments ofthe invention above described one or more of said anticreeper-bars E are fastened to a number of the ties or railesupports and abut at one or both ends against Ioo the an le-bars Dor equivalent stop members y secure to the rails. Thelongitudinalstrains to which the rails are subjected by the traiflc i are thereforetransmitted bythe anticreeperbars to the several ties to whichl they are fasof s uch ties'and ei ctually resisting creepin tened, thus distribting the strains over all.

of the rails. In ot er words, the use of suc the ties or supports to which said bars are Fas l tened. These bars are simpley in eonslruetion and their eost is ooinpaialivelyfsinall, and as they are continuous and eoexten'sive with a plurality of ties they can be applied to the track more readily than a series of arate devices which must be individually applied to the rails and ties.

l claim as my' invention 1. The combination of the rails, the ties or supports thereof, a stop member seeuredto the rails7 and a longitudinal antiereeper-bar secured to a pluraht)Y of said supports and abutting cndwise against said stop member, whereby the longitudinal strains received b y the rails are transmitted to and distributed over a. number of the ties or supports by the antiereeper-bar, substantially as set forth.

2. The combination of a pairol" adjoining' rails, the ties or supports thei'eol, plates von#v neetinpr the adjoining ends of the rails, and a longitudinal antieIeeper-lmi' pluralitjr ol' the rail-supports and abutting at its end against said eonneeting-plate, substantially as set forth.

3. The eolnbinatioii of" a series ol" rails. the. ties oi' supports thereofjplaleseonnei-tingthe adjoining ends ol the rails, and a l1 nal antieieeper-bar'secured lo a plurality ot lastel'ied to a ngitudi- 4 the ties, `said bar extending from the connerling-plaie ol'V one rail-joint to the een- 1 neet ing-plate of the next joint and abutting i at ils ends against said plates, sulistantialljY j as sel forth.

4. The combination of a pair of adjoining rails, the ties or supports thereof, plates oonneetine; the adjoining ends of the rails, a lonj `gitndinial ain-icreeperbarfastened to a plurality el" the. railsupports and abutting at its l end against said connecting-plate, and means j for fastening the antiereeper-bar to the portions of the rails, between the ties, substantially as set Jforth.

5. The combination of a pair oi' adjoining j rails, the ties or supports thereof, plates een i neeting the adjoining ends of the rails, and j longitudinal antiereepor-ba-rs a rranged on opposite sides of the rails and seeured to a i plurality of the ties and abutting at their i ends avainst said eonneeting-plates, lsubstantially as set tort-h.
